An impressive transformation.

Brake Energy Regeneration
in the BMW ActiveHybrid X6.

Until now, taking your foot off the accelerator meant that energy was going unused. However, thanks to BMW's Brake Energy Regeneration, this is no longer the case. The BMW ActiveHybrid X6 transforms the vehicle's kinetic energy into electricity. The two electric motors charge the high-voltage battery up to 120 kW (162 hp) and slow down the BMW ActiveHybrid by up to 0.3 g – the additional disc brakes only have to intervene during particularly heavy braking.
